IM PRQVEMENT INCAR-AXLE BEARINGS.

Specification forming part of Letters Patent No. 2l6,l65, dated June 3,1879; application filed February 17, 1879.

To all whom it may concern:

Be it known that I, HENRYW. FARLEY, of Oswego, in the county of Kendall,and in the State of Illinois, have invented certain new and usefulImprovements in Anti Friction Bearings for Oar-Journals; and do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being bad to the accompanying drawings, making a partof this specification, in whicha journal and its bearing upon a lineparallel with the track; and Fig. tis a central longitudinal section ofsaid axlejournal and its box, one of the friction-rollers being shown inside elevation.

Letters of like name and kind refer to like parts in each of thefigures. v

The design of my invention is to render practicable the employment offriction-rollers for journal-bearings of car-axles; and to this end itconsists, principally, in combining with the journal of a car-axle twopairs of anti-friction rollers, which furnish bearin gs for the endportions of said journal immediately outside each end of the box,substantially as and for the purpose hereinafter specified.

It consists, further, in an axle-journal which has a bearing uponsuperimposed anti-friction rollers, and is held in longitudinal positionby means of circumferential enlargements that engage with thejournal-box, substantially as and for the purpose hereinafter shown.

It consists, further, in the peculiar construction of the journal-boxand its combination with the car-journal and anti-friction rollers,substantially as and for the purpose hereinafter set forth.

It consists, finally, in the bearingas a whole, its several parts beingconstructed and combined to operate in the manner and for the purposehereinafter shown and described.

In the annexed drawings, A represents the frame of a car-truck which isprovided upon each side withtwo downward-projecting jaws,

B, for each axleemployed, said jaws being connected together at theirlower ends by means of a brace-rod, 0, all in the usual manner.

Between each pair of jaws B is fitted a pedestal or journal-box, D,which has consideraits lower end upward to or above the vertical centerof said box, has parallel sides and a semicircular top, and at each ofits edges is provided with a rabbet, d, as shown in Fig. 4.

Upon each side of the central recess or opening, cl, is" provided asimilar but more narrow recess, d which extends somewhat above thecenter of the box D, and at its upper semicircular end is curvedslightly outward from saidrecess d. i

Within each recess d is journaled a shaft, E, which projects beyond eachside of the box D, and upon each end has secured a roller, E, that hassuch diameter as to cause its periphcry to approach nearly to theperiphery of a similar roller, E, that is secured upon a shaft, E, whichis journaled within the opposite recess d. Each of said rollers has,preferably, a thickness equal to one-half the thickness of said box, andis arranged so that its inner face just clears the contiguous face ofsaid box.

The central recess, 01, of the box D receives the journal f of acar-axle, F, which journal has such reduced diameter at its longitudinalcenter as to enable it to fit loosely into said recess, and at each endof such reduced portion is provided with circumferential enlargementsj,that fit into and loosely fill the rabbets d, while immediately outsideof each enlargement said journalfurnishes a bearing for the peripheriesof the rollers E at that side of the box.

A rod or bolt, G, passing horizontally through the lower portion of thebox D, prevents the latter from becoming disengaged from the journal fin the event of the removal of the truck-' frame, or in case the truckis thrown from the "track.

The operation of the parts described is as follows, viz: The weight ofthe car is, through any desired system of springs, imposed upon theboxes D, and said boxes are sustained upon or by the rollers E and theirshaft-s E, while said rollers rest upon and are supported by thejournals f of the axles F, said rollers operating as rolling bearingsfor said journals. In consequence of the difference in the relativediameters of the journals f and rollers E the latter make but onerevolution to three revolutions of the former, by which means therubbing bearingsurfaces (the shafts E) move with, but one-third thevelocity of an ordinary axlejournal, and have materially less friction,while, by causing each axle E to bear one-half the superimposed weightsuch friction is still The enlargement f of the further reduced. journalf receives the end-thrust and preserves the longitudinal position of theaxle with relation to the journal-boxes. They may also be used as guidesfor the rollers E, if desired, and operate to maintain the longitudinalposition of the latter.

It will be observed that by placing therollers E at the sides of thejournal-boxes any desired diameter can be given to said rollers withoutinterference with the vertical motion of said box, while,as heretoforeemployed, said rollers have been placed within the box, and theirdimensions were of necessity limited to a very small size.

This invention is intended for use upon. all kinds of rolling-stock,such as is used upon the various kinds of railways, tram-roads, &c.

Having thus fully set forth the nature and merits of my invention, whatI claim as new is 3. The journal-box D, provided with the centralrecess, d, and side recesses, 01, in combination with the journal f andwith the shafts E and rollers E, substantially as and for the purposeset forth.

4. The h ereinbefore-described anti-friction bearing, consisting of thejournal-box 1), provided with the central recess, d, rabbets cl, andside recesses, d, the shafts E, and rollers E, and the journal f, havingthe reduced central portion and the circumferential enlargements f, saidparts being combined with each other and with the truck-frame in themanner and for the purpose substantially as shown anddescribed.

In testimony that I claim the foregoing I have hereunto set my hand this3d day of December, 1878, at Springfield, county of Clarke, State ofOhio.
